Inlining functions with local variables can lead to excessive stack usage with KASAN:
drivers/net/wireless/wl3501_cs.c: In function 'wl3501_rx_interrupt': drivers/net/wireless/wl3501_cs.c:1103:1: error: the frame size of 2232 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
Marking a few functions as noinline_for_kasan avoids the problem
